专利号:WO-0112791-A1 优先权日:1999-08-12 标 题 :Dna shuffling of dioxygenase genes for production of industrial chemicals 发明人:SELIFONOV SERGEY A; NEWMAN LISA M 权利人:MAXYGEN INC; SELIFONOV SERGEY A; NEWMAN LISA M 摘要:This invention provides improved polypeptides, including dioxygenases, dehydrogenases, ligases and transferases that are useful for the biocatalytic synthesis of compounds such as α-hydroxycarboxylic acids, and aryl- and alkyl-hydroxy and carboxylic acid compounds. The polypeptides provided herein are improved in properties such as regioselectivity, enzymatic activity, stereospecificity, and the like. Methods for obtaining recombinant polynucleotides that encode these improved polypeptides are also provided, as are organisms that express the polypeptides and are thus useful for carrying out said biocatalytic syntheses. Also provided by the invention are methods for increasing said solvent resistance of organisms that are used in the synthetic methods.
